To allow smooth movement of a second shell without needing high dimensional accuracy and assembly accuracy in a cabin extension structure.SOLUTION: An extension structure 20 includes: a hydraulic cylinder 50 configured to move a second shell 40; and a load receiving part 60 which is provided on an upper surface 41 of the second shell 40 to receive a load from the hydraulic cylinder 50. The hydraulic cylinder 50 has a metal fitting 58 which is provided at a tip to apply a load to the load receiving part 60. The load receiving part 60 has: an upper load receiving part 62 for receiving the load from the metal fitting 58 and moving the second shell 40 upward when the hydraulic cylinder 50 extends; and a lower load receiving part 65 which is provided below the upper load receiving part 62 to receive the load from the metal fitting 58 and move the second shell 40 downward when the hydraulic cylinder 50 contracts.SELECTED DRAWING: Figure 7

    【課題】キャビンの拡張構造に高い寸法精度や組立精度を必要とすることなく、第2シェルのスムーズな移動を可能とする。【解決手段】拡張構造20は、第2シェル40を移動させる油圧シリンダ50と、第2シェル40の上面41に設けられ油圧シリンダ50から荷重を受ける荷重受け部60と、を備え、油圧シリンダ50は、先端に設けられ荷重受け部60に荷重を与える金具58を有し、荷重受け部60は、油圧シリンダ50が伸長すると金具58から荷重を受け第2シェル40を上方に移動させるための上側荷重受け部62と、上側荷重受け部62の下方に設けられ、油圧シリンダ50が収縮すると金具58から荷重を受け第2シェル40を下方に移動させるための下側荷重受け部65と、を有する。【選択図】図7
